CHECK GAS PRESSURE and ELECTRICAL INSTALLATION - MILLIVOLT
1. Check gas type. The gas supply must be the same
as stated on the appliance's rating decal. If the gas
supply is different from the fireplace, STOP! Do not
install the appliance. Contact your dealer immedi-
ately.
. To ease installation, a 4" (610 mm) flex line with
manual shut-off valve has been provided with on
this appliance. Install and attach 1/" gas line onto
shut-off valve.
3. After completing gas line connection, purge air from
gas line and test all gas joints from the gas meter
to the fireplace for leaks. Use a solution of 50/50
water and soap solution or a gas sniffer.
4. To adjust flame height, turn HI/LO knob to HI to get
maximum pressure to burner. Turn HI/LO knob to
LO to get minimum pressure.
5. To check gas pressures at valve, turn captured
screw counter clockwise  or 3 turns and then place
tubing to pressure gauge over test point. Turn unit
to high. Figure 47 After taking pressure reading,
be sure and turn captured screw clockwise firmly
to reseal. Do not over torque. Check test points for gas
leaks.
